Be it known 'th'a-t I, AUGUSTUS CAsE, a

"citizen of the United States, residinggat Tillamook, in the county ofTill'amook and State of Ore on, have invented certain new and usefulmprovements in Bushing-Removing Tools, of which the following is a Iparticularly to the-class of bushing remov- 111% tools.

he primary object of the invention is the provision of a tool ofthischaracter, wherein the bushings fitted within the/knuckles or king boltsleeves of turning spindles of the front axles of an automobile can bereadily removed with despatch, .the tool being of novel construction sothat the same can. be applied within the knuckle or sleeve to en-.

gage the inner end of a bushing whereby it 'may be extracted by' ahammer blow upon thetool after its application, thereby facilithe tool.

tating the replacing of bushings by mechan ice in automobile repair.shops. I

Another object of the inventlon 1s the provision of a toolof'thischaracter, wherein the same can be used by mechanics without necessitati'ng labor and trouble'ordinarily experienced when attempting toremove. the

ing for. the removal ofthe' same bushings fitted withinthe knuckle orking ing from said knuckle or sleeve, the fork of the front axle of saidautomobile being shown by dottedlines, while the knuckle or sleevebushings and tool are shown by full lines and a portion of the toolbeing broken away.

Fig. '2 1s a perspective view of one part of Fig. 3 is a perspectiveview of the other part of said tool;

Fig. 4 is a fragmentary,"vertical, sectional view through the part ofthe tool shown in Fig. 2. I

imilar reference characters indicate corresponding parts through theseveral views inthe drawmg.

Referring to ignates a ortion of the wheel spindle and B the knuc le orking bolt sleeve thereof, which is adapted to be pivotally mounted inthe fork end C of the front axle-of an auto- 'mobile in the usual wellknown manner and when It is required to remove the bushing .within saidknuckle or sleeve *B the pivot bolt sleeve of a, wheelspindle of anautomobile, the tool being readily adjusted to assure the positiveengagement thereof with a bushwith despatch.

which is extremely simple inits construction, readily and easily appliedto facilitate the easy removal" of a bushing, thorou hly reliable andefficient in its purpose, an "inex ensive to manufacture.

ith these and other objects in view the invention consists in thefeatures of con-.

struction, combination and arrangement of arts as' will be hereinafterfully described, illustrated in the accompanying drawing and pointed outin" the claims hereunto appended. I I

In the accompanying drawing: Figure 1 is a vertical, sectional viewthrough the spindle-knuckle or king 'bolt sleeve of the front axle of anautomobile of a tool constructed in accordance with the invent-ionapplied for the removal of: a bush- A still further object of theinvention isv theprovision of a tool ofthis character,-

pin or king bolt (not shown) is removed.

from the-fork C'thereby detaching the knuckle or sleeve B for access to;the bushings 5 thedrawing in detail deswhich are pressed-into the saidknuckle or a sleeve through the opposite ends thereof to assure a ti htfit therein. I

The too for removing the bushings 5 from the knuckle or sleeve Bcomprises a of said tool and an adjustable wedge 7 constituting theother part thereof,.t shank atone end with a reduced or wrench "engagingtenninal 8 while the opposite end portion is bored and threaded toprovide a threaded socket 9 o ning through said-end portion for adjustaly'receivingthe reduced shank or'stem 6 which constitutes one part I I Ilfibeing of the required length and is formed I threaded or screw end 10of the wedge 7 I for a purpose presently described.-

- The socket end of the shank 6 is longitudis,

nally slitted as at 11 for a predetermined" distance at intervalscircumferentially thereof to provide expansible or spreading fingers orjaws 12,,wh1le the wedge 7 at the inner end of the reduced threaded orscrew portion 10 is formed with a beveled or tapered spreading surfaceor shoulder 12 to act w en the screw 10'is engaged in the socket 9 forthe expanding or spreading of said jaws or fingers 12, which arenormally conplon the fingers or jaws 12 of the shank 6 ice tracted,whereby they will be in position to have an external diametercorresponding to the diameter of the solid portion of the shanki 6, andthe expanding or spreading position of the fingers or jaws" 12 willenable the abutment thereof with the inner end of either bushing 5 whenin the knuckle or sleeve B to permit the removal of said bushingtherefrom. The wedge 7 near its outer end portion is formed with asuitable hole 14 transversely therein to receive a spanner or key topermit the easy rotation or turnin thereof when engaged with the part 6of the tool.

In the use of the tool the parts 6 and 7 are separated, the jaws orfingers 12 being normally contracted as shown in Figs. 2 and 4 of thedrawing and the said part 6 is inserted through one of the bushings 5 inthe knuckle or sleeve B and thereafter the wedge 7 is inserted in theother bushing to have its screw 10 engaged in the threaded socket 9whereupon the wedge 7 is rotated, while the shank 6 is held stationary,thus causing the shoulder 13 to act upon the fingers or jaws 12 for theexpanding or spreading thereof to the extent shown in Fig. 1 of thedrawing for the abutment of these fingers or jaws 12 with the inner endof the bushing 5 to be' removed and finally a hammer or other strikingimplement is manipulated to impart a blow to the shank 6 whereby thebushing 5 abutting the fingers or jaws 12 will be extracted to removefrom the knuckle or sleeve B, while the other bushing 5 can be readilyremoved either by the tool or other implement as will be clearlyapparent.

From the foregoing it is thought that the construction and manner of useof the tool will be clearly understood and therefore a more extendedexplanation has been omitted.

What is claimed is:

1. A tool of the character described, comprising two parts, one of saidparts being formed with a threaded socket, expansible fingers concentricto and projecting beyond said socket, and an adjusting screw formed onthe other part for engaging the threaded socket and having a taperingshoulder at its inner end for action upon the fingers to spread the sameon adjustment of the scre\ in the socket in one direction.

2. A tool of the character described, comprising a member havingexpansible fingers at one end thereof, the said member being formed witha threaded socket and located centrally relative to said fingers, and anadjustable member engaged in the threaded socket and having a taperingshoulder for co-action with the expansible fingers to spread the same onadjustment 'of said adjustable member.

3. A tool of the character described, comprising a shank having atubular end portion longitudinally slitted to provide expansiblefingers, the tubular end portion being internally threaded to provide asocket and an adjustable wedge for co-action with the expansible fingersand having a threaded portion engageable in the socket in said shank.

In testimony whereof, I hereunto aflix my signature.
